The Grand Canyon is one of life's most awesome spectacles, and a rafting trip down the Colorado River that carved this wonder is one of life's must-do experiences. Typically a 225-mile float, the classic trip takes about three weeks and hits some tough Class III-IV+ whitewater. The water is relatively chilly year-round, though the post-summer months are best for cooler temps and fewer river rats.
